The lime pool is filled with lime and water, the lime and the water are mixed to form turbid liquid, and the steel wire is placed into the lime pool, so that the performance of the steel wire can be changed. Because lime is insoluble in water, lime is easy to precipitate to the bottom in the lime pool, so that lime is unevenly dispersed in the lime pool, the soaking quality of steel wires is affected, and the treatment effect of the steel wires is affected. In addition, when the temperature in the lime pool is lower, certain influence is exerted on the solubility of lime, and the improvement of the treatment effect of the steel wire is not facilitated.

Disclosure of Invention

In order to achieve the purpose, the invention adopts the following technical scheme: a rough machining device for wire drawing comprises a lime pool, wherein water and lime are filled in the lime pool, an oil pipe is arranged in the lime pool, and a stirring mechanism used for stirring liquid is arranged in the lime pool.

The principle and the advantages of the scheme are as follows: lime and water are put into the lime pool, an oil pipe is arranged in the lime pool, hot oil is introduced into the oil pipe to heat liquid in the lime pool, so that the liquid in the lime pool is in a proper temperature range, the solubility of the lime is in a proper range, and the treatment effect of the steel wire is favorably improved. In addition, be equipped with rabbling mechanism in the pond, rabbling mechanism stirs lime and water to make lime dispersion that lime can be comparatively even in aqueous, avoid lime to precipitate in the bottom in lime pond, also be favorable to improving the effect of the processing of the performance of steel wire like this.

Preferably, as an improvement, the stirring mechanism comprises a cross frame vertically connected in the lime pool in a sliding manner, a vertical stirring shaft is rotatably connected to the cross frame, a transmission cylinder sleeved on the outer side of the stirring shaft is fixedly connected below the cross frame, and a spiral feeding section is arranged at the position of the stirring shaft below the cross frame; the stirring shaft is fixedly connected with a stirring blade on the position above the cross frame, the bottom of the stirring blade is rotatably connected with the top of the transmission cylinder, a material cavity is arranged inside the stirring blade, the bottom end of the material cavity is provided with a feed inlet communicated with the transmission cylinder, and the stirring blade is provided with a discharge outlet communicated with the material cavity; and a collecting tank positioned right below the stirring shaft is arranged at the bottom of the lime pool. Through making the vertical reciprocating motion of crossbearer to make the crossbearer can drive (mixing) shaft vertical movement, thereby can carry out vertical stirring to liquid.

Because the density of lime is great, lime downward precipitation easily in aqueous, the phenomenon of layering appears in liquid easily, consequently adopt conventional rabbling mechanism can only stir the lime of lime pond bottom, can only make the liquid of lime pond bottom disperse comparatively evenly in the transverse direction like this, but the lime quantity of lime middle part or upper portion is less to make lime in the liquid uneven dispersion in vertical direction. And through this scheme, the lime that downward deposits gets into to collect the groove, and when the (mixing) shaft moved down, the bottom of (mixing) shaft inserted to collect the groove, and the (mixing) shaft rotates the in-process, and the lime in the collecting vat passes through the spiral material conveying section and enters into the transmission section of thick bamboo to along transmission section of thick bamboo rebound. Then lime enters the material cavity of the stirring blade from the feeding hole, and the lime in the material cavity comes out from the discharging hole of the stirring blade in the rotating process of the stirring blade, so that the lime at the bottom of the lime pool is transferred to the middle-high position of the lime pool, and the lime can be dispersed in the vertical direction. Meanwhile, in the rotating process of the stirring blades, lime in the material cavity is thrown out from the material outlet under the action of centrifugal force, and the thrown lime is dispersed in the transverse direction under the action of inertia, so that the lime is dispersed uniformly in the transverse direction at the middle and high positions of the lime pool.
